well as we know if we want to test a substance to see if its a base then we use red litmus paper and for an acid we use blue litmus paper.

So if we see it turn pink then that means that are substance is an acid but it is not very strong and also has some of a base to it. If you want to see what i mean look up a PH scale. Hope this helped. :)
